Rated 4.0 out of 5.0 by Glad I Got Them I got my first one to alert me when someone drove or walked into my driveway and mounted it above my garage door. It works very well on an automobile or a person walking up on a clear area of the drive. It does not detect a person walking up between two parked cars. None-the-less, I purchased two more add-on units. One is on my front door and one is on the gate to my back yard. The units are on at night to alert me if there is an intruder around my home. The units work well for that purpose. I've only had them for a few days, so time will tell whether or not they are durable. So far, I am very pleased with my purchase. April 28, 2015
Rated 5.0 out of 5.0 by Good strong alert signal! Some reviews indicated the alert signal was not loud enough. I strongly disagree. With the vol. turned up high & alert placed in the middle of the house, the alarm can be heard from both ends of my 3300 sq ft one story spread out house, even with the tv's on. The frequency is high & perhaps the people that have difficulty hearing the signal may have a what is called noise induced hearing loss which occurs in the higher frequencies and also occurs with natural aging. I'm not being faciscious as I am a Speech and Language Pathologist. Also the sensor is on the exterior side of my 7" iron & wooden driveway gate more than 40' from the garage, yet the signal easily reaches the interior of my house. I give this a 5 star product.

Rated 2.0 out of 5.0 by Works Half The Time May have to send this back only works half the time. It is only 400 ft from the base down my drive way, bought it because our house is very secluded and far off the road so I like to know when some one is coming up the drive way. Plan to move it closer, but it's in the same place my old one was that lasted 3 yrs. Not real happy with this one right now! July 28, 2015
Rated 5.0 out of 5.0 by Chamberlain Motion Sensor with Wireless Motion Alert Tired of those pesky raccoons stealing hundreds of dollars of bird seed? The Chamberlain Motion Sensor will solve the problem. Purchased the system two months ago with an extra sensor and have had nothing but success with the system. Follow the instructions they are accurate and to the point. Sensors have two programming switches inside, switch 1 is 15 or 30 feet Detection Range, switch 2 is Low or High sensitivity. You want High sensitivity for raccoon detection. What you do with the raccoons is up to you, mine don’t like being treed with a garden hose and given a good bath… September 17, 2013
Rated 3.0 out of 5.0 by It is OK but would NOT BUY anotherone I purchased two of these units the volume even set on high is not very loud and can't be heard in the next room or upstairs. If a car passes it does not always catch it. If a person walks by the sensor to fast it sometimes does not catch it. Overall I am not satisfied and would not buy anotherone. July 22, 2015
Rated 5.0 out of 5.0 by Motion Sensor for Driveway This unit had the range I desired and was capable of adding additional sensors if I needed. I would recommend. to anyone. July 21, 2015
Rated 1.0 out of 5.0 by motion sencor sound not audible, three foot away and you cannot hear it. July 18, 2015
Rated 1.0 out of 5.0 by not what I expected sensor will not work parameters stated in sells write up. 15ft plus. what a laugh even with changing switch positions. sounds almost silent when triggered, would be missed if any noise exists in home at same time, like TV on low sound, or RADIO. believe the local garbage dump is the best place to relocate/install the device. the instructions tell about possible metal interference with units ability to work, but not the advertisement. would not have thought a metal fence or metal window frame or metal door would have killed the reception. My fault for purchase, without more research. April 15, 2015
